उत्तर

  1. Increasing order of their acidic strength: 2 > 3 > 1.
  2. Oxygen atom is electronegative and exerts electron withdrawing inductive effect (–I effect).
  3. Thus, compound (2) and (3) are more acidic as compared to (1).
  4. However, the inductive effect decreases as the oxygen in the ring moves away from the carboxyl group. Therefore, compound (3) is less acidic than compound (2).
